What would be more nerve-wracking: Showcasing your cleavage in $10 million of jewels on national TV, or following in the footsteps of major supermodels like Gisele Bündchen, Heidi Klum and Alessandra Ambrósio, who have all done it before you? Luckily, we’ll never have to find out — but Victoria’s Secret Angel Candice Swanepoel will when she hits the catwalk for this year’s Victoria’s Secret fashion show.

“They had to mold my body to be able to make [the bra], and I was really excited,” Swanepoel tells PEOPLE. “I tried to imagine after they’d done the mold, how would they make it, how it would look. My imagination didn’t do it justice. My favorite part is this beautiful 52-carat pear-shaped ruby. Every part of it is exquisite.”
Jeweler Mouawad hand-set more than 4,200 precious stones (including rubies, diamonds and yellow sapphires) in 18-karat gold to create the fantasy bra and matching belt. “I’ve never worn anything this pricey, and we have to put gloves on when we put it on,” Swanepoel shares. “It’s kind of a big ordeal. The bra comes with two bodyguards and we have to handle it with a lot of care!”

The South African supermodel says that while it wasn’t hard for her to keep her big announcement under wraps (“I want it to be a big surprise!” she says), it will be hard to keep her cool when walking in the show. “Definitely being the Fantasy Bra model is more nerve-wracking [than shooting swim] because it’s a one-time thing,” she says. “Walking around wearing $10 million does seem to make me a little bit nervous.”

What do you think of this year’s bra? Will you be tuning in Dec. 10 to see it in action?
